Gravity & Inertia Review

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

How does gravity on the moon compare to gravity on Earth?

Back

Gravity on the moon is about 1/6th that of Earth's gravity because the moon is much less massive than Earth.

Front

What happens to gravitational force as distance increases?

Back

Gravitational force gets weaker as distance increases.

Front

What happens to gravitational force as mass increases?

Back

Gravitational force gets stronger as the mass of the objects increases.

Front

What two factors affect the strength of gravity?

Back

The two factors that affect the strength of gravity are mass and distance.

Front

What would happen to Earth if there were no gravity?

Back

If there were no gravity, Earth would fly out into space.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

How does mass relate to inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is the relationship between mass and gravitational attraction?

Back

The gravitational attraction between two objects increases if both masses are increased.

Front

What is the effect of distance on gravitational attraction?

Back

The gravitational attraction decreases as the distance between two objects increases.
